Thanks a lot: I am working on pisces during my spare time and
congratulations is very important for my motivation.

status), but to be honest I had troubles finding the relevant parts.
I agree I modify the code to help me understanding it : @override, grouped
fields, constant first, debug logs ...
I can revert most of these boilerplates ... during cleanup.
I sent the patch as webrev to let other people evaluate its performance
using their own platform, work load, benchmarks ...
> Having not followed the discussion that closely, it was almost impossible
for me to extract the real modifications from boilerplate/refactoring as
your patch weights almost 3000 modified lines.
I looked at the webrev and I advocate I can discard many line changes.
As I use netbeans, it modified the code so easily... nevermind.

Ok. I mainly modified memory handling: use a renderer cache to reuse arrays
and pisces class instances to avoid too much allocations and resizing ...
stored in thread local or concurrent queue.

Thanks for your feedback too.
